The two pie charts illustrate the distribution of total water usage across various sectors in the years 1997 and 2007.
In 1997, the food industry accounted for the largest share of water usage, making up 48% of the total. This was followed by household use, which consumed 19% of the water, and the service industry, which used 13%. The building industry and manufacturing sector had relatively small shares of total water use, at 5% and 15% respectively.
By 2007, the distribution of water usage had shifted significantly. The food industry’s share decreased to 41%, but it remained the largest single sector. Household use increased slightly to 21%, while the service industry’s share also grew to 25%. The building industry’s water usage remained low at 5%, while manufacturing’s share decreased to just 11%.
Overall, it can be observed that household and service industries saw an increase in water consumption over the ten-year period, while the food industry experienced a decline. The building and manufacturing industries maintained relatively small shares throughout both years.
